BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a packing assembly with cushioning function for packing and protecting an article, e.g., a printer, a notebook computer, a scanner, a facsimile machine, or other electrical products that are easily damaged by impact.

2. Description of the Prior Art

A common packing assembly for electrical products that are easily damaged by impact mostly relies on light, well cushioning polymer, such as polystyrene. Referring to FIG. 1, it is a schematic diagram of a common packing assembly 1 for packing and protecting an electrical product 2, e.g. a scanner. The packing assembly shown in FIG. 1 includes a casing 12 and a pair of cushioning sleeves (14, 16). The casing 12 is usually made of a one-piece board of corrugated plastic material, e.g. a board of corrugated paper. The pair of sleeves is respectively formed from a polymer material.

As shown in FIG. 1, each sleeve is tightly adapted to receive one of the side ends of the electrical product 2. Similar to many typical electrical products, the electrical product 2 has a complicated profile. Therefore, each of the sleeves (14, 16) has a respective concave that suits one of the side ends (not shown in FIG. 1) of the electrical product 2, and the inner profile of the concaves generally meet the profile of the side ends to tightly accommodate it. Consequently, the pair of sleeves (14, 16) is mostly formed from polymer material that is easy to process. Thereupon, the electrical product 2 packed by the sleeves (14, 16) is disposed into the casing 12, and the casing 12 is then sealed.

However, the heavy electrical products are easily susceptible to damages caused during the packing process mentioned above; for example, the products could be accidentally dropped while being disposed by the operator into the narrow opening of the body casing, or the entire packing assembly might be subjected to impact while being transported. Once the entire packing assembly is subjected to an impact along the L direction defined in FIG. 1, a displacement will instantly occur at the sleeve relatively in front, and along with the dropping force of the electrical product, the impact to the sleeve will be multiplied, which leads to cracking in the sleeve and damage to the electrical product. Moreover, the packing process above requires more manpower to execute.

Accordingly, an objective of the present invention is to provide a packing assembly. The packing assembly comprises cushioning sleeves, and especially, once a sleeve is subjected to an impact, the packing assembly also has a construction formed from paper board that helps to reduce the impact on the cushioning sleeves.

In addition, packing assembly made of a one-piece board of corrugated plastic material, practiced nowadays, also has many cushioning construction designs that utilize portions of its own body to reduce impact. Please refer to U.S. Pat. No. 6,712,212, U.S. Pat. No. 6,675,970, U.S. Pat. No.

Accordingly, another objective of the present invention is to provide a packing assembly; the packing assembly includes a casing made of a one-piece board of corrugated plastic material, and especially, a portion of the casing forms a cushion construction to absorb possible impact on the article that is packed and protected by the packing assembly. Therefore, the protection provided by the packing assembly to the article is increased.

Each of the sleeves (51, 52) has a concave (not shown in FIG. 3A), and each concave is adapted to receive one of the side ends (not shown in FIG. 3A) of the article 6. In an embodiment, each of the sleeves (51, 52) is formed from a polymer material, e.g. a Styrofoam material, which is a light and effective cushioning material.

The lower casing 54 has an opening, a space, and a first side-surface portion 542. As shown in FIG. 3A, the space is adapted to tightly accommodate the article 6 packed by the cushioning sleeves (51, 52). Especially, a first supporting portion 544 is pre-formed, via e.g. die-cut mode, on the first side-surface portion 542. In the packing process of the article 6, the first supporting portion 544 bends toward the space of the lower casing 54. The bent first supporting portion 544 abuts, via a side edge thereof, against one of the cushioning sleeves (51, 52) to reduce the impact once subjected to said one cushioning sleeve. For example, the first supporting portion 544 abuts, via a side edge 5442 thereof, against the shoulder 512 of the sleeve 51 in FIG. 3A.

The upper casing 56 functions to cover the opening of the lower casing 54 and to bond with the lower casing 54 to complete the packing of the article 6.

As shown in FIG. 3B, a third supporting portion 550 is pre-formed, via e.g. die-cut mode, on the first side-surface 542. The third supporting portion 550 is adjacent to the first supporting portion 544, and it bends toward the space of the lower casing 54 in the process of packing the article 6. The third supporting portion 550, via one of its side edges away from the first supporting portion 544, abuts against the sleeve which is not abutted by the first supporting portion 544, thus reducing the impact once the cushioning sleeve is subjected to it. For example, the third supporting portion 550 abuts, via a side edge 5502 thereof, against the shoulder 522 of the sleeve 52 in FIG. 3B.

Also, as shown in FIG. 3B, a fourth supporting portion 552 is pre-formed, via e.g. die-cut mode, on the second side-surface 546. The fourth supporting portion 552 is adjacent to the second supporting portion 548, and it bends toward the space of the lower casing 54 in the process of packing the article 6. The fourth supporting portion 552, via one of its side edges away from the second supporting portion 548, abuts against the sleeve which is not abutted by the second supporting portion 548, thus reducing the impact once subjected to said one cushioning sleeve is subjected to it. For example, the fourth supporting portion 552 abuts, via a side edge 5552 thereof, against the shoulder 512 of the sleeve 51 in FIG. 3B.
